Patented Man. 28, 1916.

Application filed April 21, 1914. Serial No. 833,346.

T0 all whom it may concern:

Be it known that I, HENRY J. ROTH, a citizen of the United States,residing in the borough of Brooklyn, county of Kings, city and State ofNew York, have invented certain new and useful Iniprovements inSafety-Razors, of which the following is a specification.

This invention relates to improvements in safety razors and particularlyto telescoping handles for the same, which are adapted to be easilymanipulated and firr nly held in open or closed position. The improvedhandle will be described in connection with a simple form of safetyrazor apparatus which can efiectively be used with the socalled waferrazor blade.

In order that my invention may be more clearly understood, attention ishereby directed to the accompanying drawings form ing part of thespecificatin and illustrating the preferred embodiment of my improvedapparatus.

In the drawings, Figure 1 represents in side elevation my improved razorwith the blade positioned therein and with the telescoping handle inextended position, Fig. 2 represents an enlarged view of the same, partin vertical section and part in side clevation, Fig. 3 is a view similarto Fig. 1 with the telescoping handle in closed position, and Fig. 4 isa section taken on line 41 of Fig. 3.

Referring to the draivings, the body of the razor comprises an integralframe 1 having a central web 01 hub portion 2 arranged in anapproximately horizontal plane. This web is provided with a circularcentral opening in which is mounted the ring 3 which is screw-threadedon its inner surface to receive a screw-threaded end of the handle 4.EXtending rearwardly from the central web 2 is a portion 5 of the'frameprovidl at its rear edge with an upturned flange (S. Extending forwardlyfrom the web 2 is a portion 7 ending in the usual comb-like guard 8.ferred to, which (extends rearwardly from the central web 2, hasintegral therewith a rear cross portion extending the width of theframe, side portions 10, and.a front cross portion extending across theframe in front of the central web 2, the comh 8 being formedon theforward portion of this front cross portion. The side portions 10 andtransVersely extending portions referred to The. portion 5 cf the framere-' are inclined at a suitable angle to form a supporting surface for aWafer razor-blade, which thus extends forwardly, when mounted on theholder in position for use at an acute angle to the axis of the handle4.

The upwrdly extending rear flange6 is provided with openings throughwhich set screws 6 are adjusted to form an adjustable abutment againstwhich the rear edge of the razor-blade is positioned. Set screws 6extend above the rear cross portion of the frame and closely adjacentthereto, flange 6 only extending above the set screws a sufficientdistance to form a proper bearing surface therefor. In devices of thischaracter as previ0usly constructed, a flange similar to firnge 6 hasbeen extended upwardly so far as to interfere with the operation 0shaving.

The razor-blade is positioned by means of lugs 13 extending upwardlyfrom the side edges of side portions 10 of the frame, and adapted toreceive the side edges of the razor-blade. The blade is clamped whenpositionedbetween lugs 13 by means of pivoted arms 14 which are pivotedto the rear surfaces of side portions 10 of the frame, these arms havingupwardlv and transversely extending portions 15 on their free endsadapted to extend over and clamp the side edges 01 the razor-blade whenthe same is positioned on the frame. To accomplish the proper positionof lugs 15 to coperate with a wafer razor-blade as intended, arms 14 arebent at a somewhat sharper angle than side-memhers 10 of the frame. Thedetails of the frame construction are not claimed hcrein, but only thehandle.

The handle 4 is provided with a longitudinal slot 16 extending for thefull length of the shaft 14 betwen the lower end 17 thereof and thescrew-threaded portion of rcduced diamctor on the other end which isadapted to be screwed into the centralopen i11g of the fraine 1. Asleeve 18 is mounted on shaft 4 to be telescopically extended to form ahandle. of the desired length or to he pnshed into closed position whenthe razor is to be packed in a. box. Sleeve 18 is provided with aninwardl v extending projection 1 adapted to fit within slot 16 whensleeve 18 is in its inner or closed position, projection 19 being formedby simply punching or pressing the metal of the sleeve inwardly at thedesired point. When the sleeve is extendedinto its open position s0 thatprojection 19 has passed beyond the.

end surface 17 of the shaft, the sleeve can be rotated a portion of arevo-lution so that projection 19 coacts with the end surface 17 of theshaft 4 to prevent inward movement of the sleeve. The sleeve 18 also hasits forward edge 20 bent inwardly to a s1ight extent as shown and shaft4 is given a correspondingly increased diameter as shown at 21 for aportion of its length adjacent to end 17 of the shaft. The length of theflange or raised portion 21 of the shaft is preferably slightly lessthan the distance betWeen the projection 19 and the inwardly turned edge20 of the sleeve, the result of this construction being that when thesleeve has been extended into its outer position and rotated, theprojection 19 coacts With surface 17 to prevent inward movement of-thesleeve and the inwardly turned edge 20 of the sleeve coacts with theraised edge of the enlarged portion 21 of the shaft to prevent furtheroutward movementof the sleeve,

which latter is thereby locked against axial movement either up or doWnthe shaft 4.

Having now described my invention, what I c1aiin and desire to protectby Letters Patent is as follows:

1. In a safety razor, the combination of a handle comprising acylindrical shaft adapted to be secured 'to the blade-holder of therazor having a longitudinal groove extending throughout its length, andbeing formed With a circumferential fiange adjacent its lower end, and asleeve mounted to telescope upon said 'shaft, provided with aninwardly-extending projection integral with and pressed from the metalof the sleeve, adapted to slide in said groove and to press against therear end of said shaft when said sleeve is in extended position and isrotated about said shaft, With said projection removed from said groove,the forward end of said sleeve being providedwith an inwardly-extendingfiange adapted to coact with said shaft flange when said sleeve is inextended position, substantially as set forth.

2. In a safety razor, the combination of a handle comprising acylindrical shaft, and a sleeve mounted thereon and adapted to slidethereon into closed and extended posi- A tions, said shaft and sleevebeing formd with coacting means, integral therewith, for locking saidsleeve in its extended position against movement longitudinally of saidshaft either up or clown, said means comprising a collar portion at theend of said shaft and inwardly extending projections on said sleeveadapted to contact both upper and lower surfaces of said collar portionwhen said sleeve is arranged in its extended position, substantially asset forth.

This specification signed and witnessed this 20th day of April, 1914.
